Casting a tile with bottle glass
- November 20, 2009 at 2:03 pm #9350BOATBAGParticipant
I’d like to try casting a tile from broken bottle glass. I’ve washed, dried, & broken a standard size Skyy vodka bottle. I’m thinking about trying a 6″ square cast mold. Has anyone tried this or anything similar? I’m open to suggestions.

My off the cuff answer is “Try it and see”.
More considered view is that you will have a lot of vailing and visible edges of the glass pieces. Going to a very high temperature or with a long soak will not completely eliminate these, so you need to incorporate this into the “look” of the piece.
There is likely to be a significant amount of devitrification too.
Instead of making a mould, you can place batt washed dams to hold the glass to the size you want. You will need to do some thinking about the amount of glass you need to achieve a 6mm thick tile. This is where the metric system of measuring comes in handy.
a 10cm square tile (4″) 0.6cm thick requires a volume of 60 cubic cm of glass. Glass has a specific gravity of around 2.5. So you need about 150 gms of glass to fill the space.

Kaiser Lee Board makes a great casting mold and you can use it over and over again. On top of it you don’t have to cast squares only – you can cast any shape you can think of and make interesting paper weights out of bottle glass. In our online Gift shop you will find two pieces we have cast with bottle glass. http://fuseit.estoreadvanced.biz/index.php?p=product&id=19&parent=5 If you happen to own my Fuse It book you will find casting lessons in there.
